.SPRAYING NOZZLE FOR ENGDTES.

Application filed March as, 1921. Serial at. 456,821.

To all whom it may concern.

Be it known that I, SAMUEL B. Gem), citizen of the United States, and resident of Independence, county of Jackson, State of Missouri, have invented a certain new and useful Improvement in Spraying Nozzles for Oil Engines, of which the following is, a com plete specification.

This invention relates to spraying nozzles for oil engines, and has for its primary object to produce a nozzle in which the possibility of interruption in the flow of the oil from clogging of the nozzle, is practically eliminated. A nozzle of this character is very desirable, as in all engines with which I am familiar, operated with crude oil, especially where such oil comes direct from the wells, shut-downs due to clogging of the oil nozzles, are of frequent occurrence. These shut-downs are expensive, and they involve loss of production as well as loss of time, and it sometimes happens that the clogging of a nozzle results in the rupture of the supply piping, and sometimes, in injury, more or less invention consists in certain novel and useful features of construction and combinations of parts, as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 1 is a side elevation of an oil engine nozzle embodying the invention.

Figure 2 is a central longitudinal section of the nozzle.

Figure 3 is a cross-section on the line lll lll of Figure 2.

Figure 4 is a cross'section on the line lV-IV of Figure 2.

Figure 5 is an end view of the nozzle.-

In the said drawing, a pla comprises an angular head land a threade portion 2 for threaded plug engagement with a threaded opening the wall of an engine, (not shown}, toform a support for the nozzle 3. The p ug is smooth internally' and is formed with a forwardlyfacing shoulder 4 for engagement by a rearwardly-facing shoulder 5 formed on the nozzle, and the latteris provided at its rear end with a reduced threaded portion 6 engaged by a clamping not '2, which bears against the rear face of the l for the purpose of clamping the shoulder or" the nozzle firmly against the shoulder of the nut and thus holding the nozzle in rigid relation to the nut 1.

A nut 8 engages the rear end of the portion 6 of the'nozzle, and also fits over the flanged front end of a nipple 9, screwed upon the front end of the oil supply pipe 10 of the nozzle, said nut 8 and nipple 9 constituting -a union for securely connecting the nozzle with the oil supply pipe. The tip of the nipple 9 is of conical form as at an intermediate portion 13, and a tipwportion 14, the front end of the rear portion mg internally enlarged and threaded as at 15 and engaged by the externally-threaded reduced 7 rear end 16 of the intermediate portion 13.

The front end of the intermediate portion 13 is internally-threaded as at 1?, and is' engaged by the reduced externally-threaded rear portion 18 of the tip portion 14. By this arrangement it is obvious that the sections of the nozzle can be readily secured together or separated,

The portion 6 of the rear member of the nozzle 15 provided with a central bore 19 reduced slightly at its rear end to provide a valve seat 20, engaged by a ball valve 21,- and said valve is held upon its seat by a spring 22, fitting around the reduced stem of a 23 against which the front end of said s ring hears. Said plug is prefierably threa ed and screwed into the portion 6, and to provide for the passage of oil, the said plug is preferably flattened as at 24. It will thus be seen that the; ball valve 20 is held upon its seat'with a yielding pressure, so that when the pressure upon its opposite side or face, developed by the operation of the customary pum (not shown) used in connection with engines of this type, exceeds l the pressure of said spring, the valve will open and permit oil'to pass, said valve however'remaming closed normally so that 01] cannot leak past it.

' The rear portion of the nozzle at the point of communication between the bore of portion 6 and the enlar ement of said bore, provides a. valve seat or a ball valve 25, and engaging said valve is a pin 26, surrounded by a slpring 27, whichbears at one end against t spin and at the other end against the section 13, .for the purpose of holding valve upon its seat until a preponderating pressure is applied 11 on the said valve by theoil. It Will thus e seen that this valve 25 afl'ords a second check against the leakage of oil forwardly through the nozzle, and in practice the reslstance of spring 27 will exceed. that oflered by the s ring 22, but willof course yield when the pump heretofore mentioned, has develo ed the required pressure.

T e ti section or member 14 of the valve is provi ed at its tip end with a. flaring opening 28, provided with an exit groove 29 through which the oil' is adapted to be sprayed under the pressure from the ump. A conical valve 30 normally closes t e ti opening exceptthe exit passage 29 thereo and sald valve 30 is provided with a stem 31 diametrically reduced at its front end at 32 to provide a chamber for holdin sufiicient oil to guard against' irregu ar or spasmodic spraying action. At its rear end the stem is reduced as at "33, and between portions 32 and 33, is provided with longitudinal rooves or passages 34 to accommodate t e flow-of oil fromsection 13 to the tip ofthe nozzle. One or more nuts 35 are secured upon the rear of portion 33 of the valve stem, and a spring 36 surrounds said stem and bears at its front end against portionl of the nozzle, and at its rear end against one of said nuts 35, and thus normally holds the valve upon its seat, said spring being adapted to yield to permit the valve to be unseated by the ressure of oil,

only. in the event that the orifice 29 becomes clo ged to the ejection of oil. In the'event suc clogging occurs and the pressure of oil becomes undesirably high, the spring 36 will yield, the valve being reseated by said spring as soon as the pressure falls sufliciently'. Under normal condition the 0 ening of, the valve will result in the unc ogging of the exit passage 29, but should this not occur, the valve will continue to periodically open and thus guard against any back pressure which might rupture the supply plpe 10 or result in injury to the pumping mechanism or any part of the engine, it emg understood t at the snapping of the valve back upon its seat has a tendency 'to dislodge cloggingmatter from the orifice 29, and thus minimlze opening movements of valve 28, and such irregularity or spasmodic discharge of oilas is incidental to openin valve. tained irregularity in the operation of the engine, the nozzle can be readily detached and cleaned and quickly restored to normal condition, or the operator can ',manually manipulate the pump to impart quick opening and closing movements to the valve 30 for the purpose of dischargin clogging matter from said passage as wel as from the valve itself. a

From the above description, it will be apparent that I have produced a nozzle for oil engines, which embodies the features of and closing movements of said W on the attendant notes any susadvantage set forth in the statement of the objects of the invention, and which obviousl} may be modified in various particulars without departing from the principle of construction and mode of operation involved. I claim:

' 1. An injector for oil engines, comprising a body portion havinga dlscharge end pro-v vided with a discharge, opening of large 2 a spring surrounding the valve stem within said body and exerting a pressurethereon sufficient to close the valve when the pressure is normal withi'n'the injector," but permitting the valve toopen when the smaller opening is obstructed.

2. An injector for oil engines, comprising a body portion having a discharge end provided with a discharge opening of large area and a supplemental discharge opening of small area, a longitudinally extendin valve'stemwithin said body whose inner en is subjected to the pressure within the injector, said valve stem having at its outer end a conical head normally closing the larger opening while leaving the smaller opening unobstructed and having a reduced portion within the bod forming a chamber adjacent the conical ead, a spring surrounding the valve stem within the body, an adjustable member on the stem against which one end of the spring bears, whereby the tension of the spring may be set to hold the valve closed under I normal pressure within the injector but permit it to 0 on when they smaller opening is obstructe In witness whereof I hereunto aifix my signature.
